肤色在人类学天天被讨论,有许多不同的观点。定论一个地区的肤色从底子来说确实很难,应为因素太多的,包括文化,地理位置,城市化,经济和许多其他无数的影响。比如西北人和藏族皮肤黑是应为城市化低,那边的太阳更毒。相比来说,四川UV太低了。我上次在重庆住了两个周,太阳一次没出来,而且那边的城市很拥挤,到处都有阴影的大楼和树。我去大西北的宁夏,被太阳晒伤了,应为基本没有阴影,UV也很高。还有,大部分东亚人的肤色波动很大,很多冬天白夏天黑。整体来说,测试这方面确实难,不过我找到基因数据了。OCA2 481thr是一个等位基因(allele),负责东亚人白皮肤的基因。
按照这个调查,有这个基因最多的是蒙古东部的人,和其他北亚人。第二位是日本,韩国和中国的辽宁沈阳。第三位是北京和西安。第四是福建,湖南和苏南。第五是广东。所以东亚肤色底子大概也按照这个排名。不过看起来好像整体差距不大,所以整体来说东亚肤色都应该差不多,最大的因素还是环境。
